Mariano Rivera has 82 career wins to go with a record 651 saves. He’s puzzled about how he got that 82nd victory.

The Yankees’ Hall of Fame closer was credited with the W on Thursday because setup man David Robertson failed to hold a three-run lead in the eighth inning against the Baltimore Orioles. After the Yankees retook the lead in the top of the ninth, Rivera came in and closed out the victory.

According to seldom-applied Rule 10.17(c), the official scorer has the discretion to award the win to another pitcher if the pitcher of record was “brief and ineffective” in his outing. Scorer Mark Jacobson thought Robertson’s one-inning, three-run outing fit the criteria, and thought Rivera was more qualified for the win.

A day later, Rivera was still mystified as he tried to apply baseball logic.

“I have gotten wins when I blow the save but I come back and hold the inning. Then our guys score the next inning and I have got that win. . . . Never, never, never have I seen this before. That’s not baseball to me. If you have the lead, and hold the lead, that’s a save,” he said, according to the New York Daily News.

“We won and that’s the important thing. But I’m interested to know why I get the win. Who got the save then? It was a save situation. If I give up a run there, I get a blown save, right? So where does the save go? Someone saved the game, so who is that person? It’s just weird. Never heard of anything like that before.”
